MusicCaps: A Dataset of High-Quality Music Captions for AI

MusicCaps is a dataset containing 5,521 music examples, each meticulously labeled with an English aspect list and a free-text caption crafted by musicians. This dataset is designed to facilitate research and development in AI-driven music understanding and generation.

What is MusicCaps?

MusicCaps is a valuable resource for anyone working on AI models that need to understand or generate music. It provides detailed textual descriptions of music clips, focusing on the sonic qualities and characteristics of the music itself.

How does MusicCaps work?

Each entry in the MusicCaps dataset consists of a 10-second music clip sourced from the AudioSet dataset, accompanied by two forms of textual description:

1. Aspect List: A structured list of attributes describing the music, such as genre, instrumentation, and sonic qualities (e.g., "pop, tinny wide hi hats, mellow piano melody, high pitched female vocal melody, sustained pulsating synth lead").
2. Free-Text Caption: A multi-sentence description of the music, providing a more narrative and detailed account of what the music sounds like (e.g., "A low sounding male voice is rapping over a fast-paced drums playing a reggaeton beat along with a bass. Something like a guitar is playing the melody along. This recording is of poor audio-quality. In the background, a laughter can be noticed. This song may be playing in a bar.").

Key Features of MusicCaps

• High-Quality Captions: The captions are written by musicians, ensuring accuracy and a nuanced understanding of the music.
• Focus on Sonic Qualities: The text descriptions concentrate on how the music sounds, rather than metadata such as artist names or song titles.
• Based on AudioSet: The music clips are taken from the AudioSet dataset, providing a diverse range of audio examples.
• Structured and Unstructured Data: The combination of aspect lists and free-text captions offers both structured and unstructured data for training AI models.

How to use MusicCaps?

1. Download the Dataset: The dataset is available for download as a CSV file (musiccaps-public.csv).
2. Explore the Data: Each row in the CSV file contains the YTID (YouTube ID), start and end times of the music clip, AudioSet labels, the aspect list, the caption, and other metadata.
3. Use the Data for AI Training: The dataset can be used to train AI models for tasks such as music captioning, music generation, and music understanding.

Why choose MusicCaps?
